What P2727 means
P2727 is set when the control circuit of solenoid E is open, so no current can flow through the coil. GM's eight-speed table checks the clutch 5 valve for an open-circuit flag over 0.3 s, and on the Allison 1000 the test on PCS 1 is rated Type A. The 2023 Corvette dual-clutch TCM looks at its system pressure pilot valve while switched off: a sense voltage between roughly 1.7 and 3.0 V means open load, confirmed after 150 ms (Type A). Ford's TR9070 maps open load of its line pressure pilot valve to the same code. A field case without wiring damage exists: GM's PIP5646 series for 2019-2020 Silverado and Sierra with the 8L90 names P2727 among the codes behind sudden rear-wheel lock-up and replaces the TCM.
P2727 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2727
- MIL on and limp-home gear
- Rear wheels may lock at low speed (GM 8L90 case)
- Harsh or missing shifts
Common causes of P2727
- Most likelyBroken wire or backed-out pin
- PossibleOpen winding in solenoid E
- PossibleInternal TCM fault (GM 8L90, PIP5646)
- Less likelyConnector not latched
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2727 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 27 | The exact fault in that area. |
What to do next
- Note P2727 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2727
What does P2727 mean?
P2727 means "Pressure Control Solenoid E Control Circuit/Open". P2727 is set when the control circuit of solenoid E is open, so no current can flow through the coil. It is a generic code, so it means the same on every make.
Is it safe to drive with P2727?
Drive gently and only to a workshop. With P2727 the car can go into limp mode (reduced power) to protect itself.
Will P2727 fail an emissions test?
Yes, it can. P2727 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2727 to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2727 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
